I'm rehabilitating a 1972 XS2 with the goofy, one-year-only, front hub/brake setup. While rebuilding the front brake caliper and installing a new front tire, I discovered that the front axle is bent, although the front wheel doesn't show any sign of damage. Unfortunately, I'm having a hard...

I expect some of you are familiar with the points/advance housing delete covers offered by Hoos Racing and Heiden Tuning. If a crank timed ignition is used (e.g., Vape/PowerDynamo, Electrex, PVL, etc.) these allow for removing the points/advance housings to clean up aesthetics. Heiden Tuning...

I'm continuing to make progress on my previously dormant Redline frame XS650 street tracker project, and have started considering exhaust options. With the kickstarter, brake lever, and rear master cylinder linkage, the right side of the bike seems a bit busy for a right side mount 2-into-2...

What's the purpose of the left engine case cover gasket? The 1970 engine that came in my Redline frame bike didn't have one, but the parts diagram shows there's supposed to be one there. Easy enough to order and install, I'm just curious.

I noticed this listing on the MotoGadgets site indicating that an XT500 folding shift lever can be used on an XS650. Can anybody confirm compatibility? MotoGadgets XT500 Shift Lever

This relates to a 1970 XS650 (XS1) engine. Since I'm installing a Vape/PowerDynamo crank triggered ignition, I removed the points/advance mechanisms and housings (#21 in the parts diagram) and am installing Heiden Tuning covers for aesthetic reasons. When I removed the housings, they were only...

I'm trying to put a long dormant Redline framed XS650 back on the road with some modern upgrades. The engine is a 1970 and it appears to be in stock tune. I considered running a single Mikuni VM carb on one side to accomodate a high mount exhaust on the other side, but have discovered the...

As found in a 1970 engine:

I recently purchased this 1973 XS2 and do not want to keep the faring, front crashbars (with highway pegs), or sissy bar. So offering them for free to whoever wants to pick them up in Redwood City, California. The rear crash bars might be thrown in as well if it turns out they are not Moto...

Purchased last weekend from the original owners family. Running and very low miles but some "shelf wear" from being stored in an unheated San Francisco garage. These are as purchased pics. I'll post additional pics with the accessories removed in another post.

I saw this advert for an extremely nice XS1 on Craiglist and thought somebody here might be interested. I expect there are only a handful of early bikes in similar condition. https://sacramento.craigslist.org/mcy/d/sacramento-1971-yamaha-xs-650/6788679593.html Note this isn't my bike, and I...

Clutch questions directed to the resurrection of a crusty 1970 XS1/XS650. . . . The (6) fiber clutch plates measure 3.5mm thick and the (5) metal plates measure 1.56mm thick, which seems to be in spec. On the downside, the left engine cover has a long crack at the rear on the top side and the...

My 1970 XS1 came with a very stuck engine, which is now out of the frame. I removed the head and have managed to free up the pistons courtesy weeks of soaking in ATF, a blowtorch, and a small sledge. The cylinders need to come off, but there is a web cast into the cylinders that prevents...

I have a set of NOS Red Wing 34mm forks that I want to install on my 1970 XS1 project to replace the original rusty fork. For the Red Wing forks to work I need a top triple clamp that actually clamps the tubes, as opposed to the current top triple clamp where the tubes are just fitted into the...

I'm in the process of getting a 1970 XS1 back on the road, and I'm considering swapping in a cush-drive rear hub. I've read some posts here about cush-drive rear hub alternatives (e.g., TX500, TX750), but it's not clear as to which is the most plug-and-play alternative?

I need to buy 256-type pistons for a 1970 XS1 and I'm trying to figure out the pros and cons of NOS vs. new production OEM type pistons. New production pistons like those sold by Heiden Tuning are described as having the "latest modern thin piston rings." What specific benefits does that...

Does anyone know if the pistons in the 750 Big Fin 9:1 CR kits from Heiden and Mikes XS can be machined to achieve lower compression on the order of 8:1 to 8.5:1? http://www.xs650.com/forums/the-garage.2/create-thread https://www.mikesxs.net/yamaha-xs650-447-big-bore-kit-80mm-750cc.html Or...

I'm contemplating a 19-inch rear wheel conversion on a '70 XS1 and am wondering if there are any swingarm clearance issues to consider? My plan would be to lace up a new, 19-inch Excel alloy rim to the stock hub.

What chassis parts are unique to the XS1 / XS1B models? Please add to this list: *front fork *front fender + brace *front (drum) brake *seat grab rail *rear brake plate
